Hi Mike Yes we have done some cool things with Expresso machines for extracting a small amount of liquid from biochars but industrially we use emulsifiers or the design i have posted before with a hea

Hi Kelpie Mikes suggestions are good ones to try. The volatile content of wood biochar at 650C is very small and very different to low temperature bochars especially from grasses and straw. Unfortunat

Hi Kelpie I would use a combined biochar wood vinegar foliar spray. Basically take a low temperature (400-450C) straw biochar and dilute 20 to 1. Heat for 30 minutes at 90C while stirring and then fur

Hi Kathleen Is this approved by one of the organisations buying carbon credits. Regards Stephen

You need to do a further graph taking away the amount of biochar you added to give you an indication of the new soil SOC. Note to do properly requires a lot more analysis. If you wish to see the techn

Our work indicates make a liquid slurry that has a nutrient rich colloidal biochar mineral complex and spray with a boom onto the surface for pasture and turf is cheaper requires less biochar (about 1

Hi Kathleen et al Isnt it better to have recommendations that align biochar based products to specific soil constraints. This is a decision tree that Paul Taylor Lukas van Zwieten and Annette Cowie ha

Tom Thats a very low yield. Typically for 70%C in biochar yields are 30-33% (depending on ash content) in trough pyrolysers. My design uses flaming pyrolysis and water spray injection to achieve high

You can use liquid chromatography with organic carbon detection as the best method as this is a size exclusion technique and gives you numerical concentration of different classes of organics based on

All I have posted a number of times the various papers that we have published on the overall benefits of feeding animals with biochar and allowing dung beetles to bury this carbon. It is probably the

Hi gerry I couldnt access the link you gave Can you email please. Regards Stephen

Dear Monica You may also like to connect with Brenton Ladd in Peru. Regards Stephen

Also adding bags of biochar into nutrient rich lacks and ponds. I noted a nice lecture by James Gaspard on this technique. I have used it in my aquaponics system to remove nitrates but you need to aci

By the way I just found this which is pretty impressive https://www.arti.com/charged-up-biochar-from-artis-solar-powered-water-biofilter/?utm_source=rss&utm_medium=rss&utm_campaign=charged-up-biochar-

There was a very neat U tube of floating raft of biochar buckets attracting algae to clean up algal blooms. Cant find it so if anyone has this video can they post the location as this was a great exam

Hi Trevor We have had success with biochar based reactive barriers capturing nutrient and salt run off. Regards Stephen

Hi Kelpie Most continuous reactors I work with the biochar comes out of the outlet auger at 250C. We normally recommend adding sufficient liquid to have a 20-30% moisture content for safe transportati

Hi Don But if you pyrolyse at low temperature with acid catalysts like clay you get low pH and you get the greatest plant and beneficial microbial response. it is so important that people understand t

Paul Have they read the recent article that our group (How Biochar works) and Hans Peter et al have written to show the evidence Its really important when you approach these groups to show them that t

Nando You should look at Hans Peters article on feeding biochar to animals and the article we wrote on feeding biochars to cows at Doug Pows farm. In Norway Standard Bio sells a great biochar to farme
